TPB #90 – Analyzing Error in the Projectile Sensor

Posted by:

The error of the Camera Axe’s projectile sensor is analyzed. Experiments are done in software to isolate the error which turns out to come almost entirely from the 4 microsecond granularity of the Camera Axe’s timer hardware. Then math is done on that 4 microsecond granularity to determine how that affects the reported speed of the bullet in the Camera Axe and the positioning of the bullet in a photo.

For a ...

TPB #84 – Weather Proof Motion Sensor

Posted by:

I show how to make a weather proof motion sensor for the Camera Axe. Most of the video is about how the case is made, but I also touch on the fact that this sensor is more accurate than the standard Camera Axe motion sensor because it uses I2C instead of analog values to report distance.

Schematic

Code (5.5 or newer an you must enable max sonar menu)

Part List:
* Sonar

TPB #17 – Clip Sensor

Posted by:

This week I discuss the clip sensor. This is a very versatile sensor has two alligator clips and detects open or short circuits. In this video I show how to make a pressure sensor with some tinfoil, wire in a nice manual switch, and make a tripwire.

The schematics and parts list for this sensor are here, or you can buy is from the Camera Axe Store.

TPB #15 – Camera Shutter Sync Sensor

Posted by:

In this episode I explain what the Camera Shutter Sync Sensor can do with the Camera Axe.

One use is to alternate between two banks of flashes on each shot. This has a few potential uses. For example each bank of flashes could be setup to give different lighting to the scene. Then with two rapid shot you get the same pose with two different lighting effects. Another example would be ...
